  3. Select Screen lock, then select the desired Screen lock. Follow the prompts to set up your security lock.
    Note: If you choose a Pattern lock, you must remember your pattern. If you forget your pattern, the only option is to perform an alternate master reset of your device, which will erase all personal information.
